So the greatest common factor 65,60,830 is 5.
Lets's calculate LCM of 381,151,846
3 | 381, 151, 846 |
127, 151, 282 |
∴ So the LCM of the given numbers is 3 x 127 x 151 x 282 = 16223742
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/16223742
Therefore, the GCF of Fractions 65/381,60/151,830/846 is 5/16223742
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 381,151,846 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(381,151,846) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(381,151,846) x common factors =1 x 3 = 3
LCM(381,151,846) = ( 381 × 151 × 846 ) / 3
LCM(381,151,846) = 48671226 / 3
LCM(381,151,846) = 16223742
